  1. Imagine Wissen Technology is experiencing a surge in user signups for its flagship AI-powered learning platform. Our current database architecture, designed for a smaller scale, is showing signs of strain, leading to slow API response times for new user onboarding. Describe how you would diagnose and address this performance bottleneck. Focus on database indexing strategies and potential caching mechanisms suitable for a rapidly growing user base.

    Software EngineerSystem DesignTests: Evaluates ability to handle scale, diagnose performance issues, and design resilient database solutions.

  2. Wissen Technology's platform offers personalized learning paths. A common bug reported by users is that their progress tracker occasionally resets. This occurs intermittently and is hard to reproduce. Walk me through your debugging process, from initial report analysis to pinpointing the root cause and proposing a fix.

    Software EngineerDebuggingTests: Assesses systematic problem-solving and debugging skills in a complex application.

  3. We are developing a new feature for the Wissen platform that allows instructors to generate automated quizzes based on uploaded course materials. This involves significant text processing and natural language understanding. Propose a high-level system architecture for this feature, considering scalability, latency, and potential integration with existing services.

    Software EngineerSystem DesignTests: Tests architectural thinking, understanding of distributed systems, and integration strategies.

  4. A core component of Wissen's platform is its recommendation engine for courses. We've observed a decrease in click-through rates for recommended courses. Outline the steps you would take to identify the cause. Consider potential issues with data freshness, algorithm drift, or user behavior changes.

    Software EngineerReasoning & AlgorithmsTests: Measures analytical reasoning and understanding of algorithmic performance in a live system.

  5. Design a rate limiter for the API endpoints that serve course content on the Wissen platform. The goal is to protect our backend services from abuse and ensure fair usage for all users. Discuss different algorithms and trade-offs, considering factors like accuracy, memory usage, and ease of implementation at scale.

    Software EngineerSystem DesignTests: Evaluates understanding of distributed system constraints and practical API management.

  6. Wissen's platform aggregates learning data from various sources. We need to build a system to detect and flag duplicate learning records to ensure data integrity. Describe the challenges you foresee and propose a data processing pipeline to achieve this, considering efficiency for a large dataset.

    Software EngineerData Structures & AlgorithmsTests: Tests knowledge of data processing, efficiency, and handling data quality issues.
